I talk about it openly which helps a lot..especially at work. Once i didn’t try to mask it, I felt more comfortable in speaking situation and my fluency became much much better. That’s just me though. I have a job where I speak A LOT and no one cares if I get a block or 20 during a long meeting where I need to speak. That’s not to say I don’t have bad days where I feel I can’t get a word out. But I just roll with it.
